Chapter 4: Becoming Physically Fit
Across
- 4. – the ability of the heart, lungs, and blood vessels to process and transport oxygen required by muscle cells so that they can contract over a period of time; cardiorespiratory endurance is produced by exercise that require continuous, repetitive movements.
- 5. – arthritis that develops with age; largely caused by weight bearing and deterioration of the joints.
- 8. – muscular strength training exercises in which the resistance is so great that the object cannot be moved.
- 15. – drugs that function like testosterone to produce increases in muscle mass, strength, endurance, and aggressiveness.
- 16. – the length of exercise time of each training session; for aerobic fitness 20 to 60 minutes per session is recommended.
- 17. – the component of physical fitness that deals with the ability to contract skeletal muscles to a maximal level; the maximal force that a muscle can exert.
- 19. – the principle whereby a person increases the resistance load to levels above which he or she is normally accustomed to; this principle also applies to other types of fitness training.
- 21. – the ability of joints to function through an intended range of motions.
- 22. – the number of times per minute the heart must contract to produce a cardiorespiratory training effect.
- 24. – a set of attributes that people have or achieve that relates to the ability to perform physical activity.
- 25. – decrease in bone mass that leads to increased incidence of fractures, primarily in postmenopausal women.
Down
- 1. – muscular strength training exercises in which machines are used to provide variable resistances throughout the full range of motion at a fixed speed.
- 2. – the body’s alternative means of energy production, used when the available oxygen is insufficient for aerobic energy production; anaerobic energy production is a much less efficient use of stored energy.
- 3. – the absence of menstruation.
- 6. – the body’s primary means of energy production, used when the respiratory and circulatory systems can process and transport sufficient oxygen to muscle cells to convert fuel to energy.
- 7. – a “bouncing” form of stretching in which a muscle group is lengthened repetitively to produce multiple quick, forceful stretches.
- 9. – any bodily movement produced by skeletal muscles that results in energy expenditure.
- 10. – muscular strength training exercises in which traditional barbells and dumbbells with fixed resistances are used.
- 11. – the ability of skeletal muscles to perform contractions; includes muscular strength and muscular endurance.
- 12. – A reduction in the size of the muscle fibers, related to the aging process.
- 13. – the level of effort put into an activity; for aerobic fitness 40% to 85% of heart rate range is recommended.
- 14. – the aspect of muscular fitness that deals with the ability of a muscle or muscle group to repeatedly contract over a long period of time.
- 18. – the slow lengthening of a muscle group to an extended stretch, followed by a holding of the extended position for 15 to 60 seconds.
- 20. – the number of exercise sessions per week; for aerobic fitness three to five days are recommended.
- 23. – a subcategory of physical activity; it is planned, structured, repetitive, and purposive in the sense that an improvement or maintenance of physical fitness is an objective.
